Where does your stuff come from? (Check the tags on your clothes, shoes, watch, calculator, etc.)

Why have your clothes and personal items traveled all around the world?

Why do people trade?1. Assume people didn’t trade. What things would

you have to go without? Everything you don’t produce yourself!

(Clothes, car, cell phone, bananas, heath care, etc)The Point: Everyone specializes in the production

of goods and services and trades it to others 2. What would life be like if cities couldn’t trade

with cities or states couldn’t trade with states?Limiting trade would reduce people’s choices and

makes the worse off. The Point: More access to trade means more

choices and a higher standard of living. 4

Per Unit Opportunity Cost Review

Assume it costs you $50 to produce 5 t-shirts. What is your PER UNIT cost for each shirt?

$10 per shirtNow, take money our of the equation. Instead of

producing 5 shirts you could have made 10 hats.

1. What is your PER UNIT OPPORTUNITY COST for each shirt in terms of hats given up?

1 shirt costs 2 hats 2. What is your PER UNIT OPPORTUNITY COST for

each hat in terms of shirts given up? 1 hat costs a half of a shirt

Per Unit Opportunity Cost ReviewRonald McDonald can produce 20 pizzas or 200 burgers

Papa John can produce 100 pizzas or 200 burgers1. What is Ronald’s opportunity cost for one pizza in

terms of burgers given up?2. What is Ronald’s opportunity cost for one burger in

terms of pizza given up?3. What is Papa John’s opportunity cost for one pizza in

terms of burgers given up?4. What is Papa John’s opportunity cost for one burger

in terms of pizza given up?

7

Ronald has a COMPARATIVE ADVANTGE in the production of burgers

Papa John has a COMPARATIVE ADVANTAGE in the production of pizza

1 pizza cost 10 burgers

1 burger costs 1/10 pizza

1 pizza costs 2 burgers

1 burger costs 1/2 pizza

Page 8: Why do people trade?

Absolute and Comparative AdvantageAbsolute Advantage• The producer that can produce the most output OR

requires the least amount of inputs (resources)• Ex: Papa John has an absolute advantage in pizzas

because he can produce 100 and Ronald can only make 20.

Comparative Advantage• The producer with the lowest opportunity cost.• Ex: Ronald has a comparative advantage in burgers

because he has a lowest PER UNIT opportunity cost.

8

Countries should trade if they have a relatively lower opportunity cost.

They should specialize in the good that is “cheaper” for them to produce.

A. Which country has an absolute advantage in the production of tractors? Explain how you determined your answer.

B. Which country has an absolute advantage in the production of cars? Explain how you determined your answer.

C. Which country has a comparative advantage in the production of cars? Use the concept of opportunity cost to explain how you determined your answer.

D. For Xanadu, what is the opportunity cost of producing one car?

E. If the two countries specialize and trade with each other, which country will import cars? Explain why?

Page 18: Why do people trade?

10 Points Possible (2 Points For EACH: 1 point answer, 1 point explanation)A. Answer-Xanadu

Explanation- Because they can produce more total tractors than Atlantis.

B. Answer-AtlantisExplanation- Because they can produce more total cars than Xanadu.

Page 19: Why do people trade?

(2 Points For EACH: 1 point answer, 1 point explanation)

E. Answer- Xanadu will import carsExplanation- Xanadu should not make cars. They should specialize in making tractors and import cars from Atlantis since they have a lower opportunity cost.

Kenya wants RadiosIf the terms of trade for 1 radio is greater than 3 pineapples then Kenya is worse off and should make radios on their own.India wants PineapplesIf the terms of trade for 1 radio is less than 1 pineapple then India is worse off and should make pineapples on their own.

What terms of trade benefit both countries?

Page 22: Why do people trade?

Trading 1 radio for 2 pineapples will benefit bothIf Kenya produces radios by themselves, they give up 3 Pineapples for each radio. If they can trade 2 pineapples for each radio they are better off. If India produces pineapples by themselves, they give up 1 pineapple for one radio. If they can get 2 pineapples for one radio they are better off.

The countries trade at a lower opportunity cost than if they made the products themselves!

Comparative Advantage PracticeCreate a chart for each of the following problems. • First- Identify if it is a output or input question • Second-Identify who has the ABSOLUTE ADVANTAGE• Third-Identify who has a COMPARATIVE ADVANTAGE• Fourth- Identify how they should specialize

1. Sara gives 2 haircuts or 1 perm and hour. Megan gives 3 haircuts or 2 perms per hour.

2. Justin fixes 16 flats or 8 brakes per day. Tim fixes 14 flats or 8 brakes per day.

3. Hannah takes 30 minutes to wash dishes and 1 hour to vacuum the house. Kevin takes 15 minutes to wash dishes and 45 minutes to vacuum.

4. Americans produce 50 computers or 50 TVs per hour. Chinese produce 30 computers or 40 TVs per hour. 23

International Trade and Finance

Page 25: Why do people trade?

Export Goods & Services 16% of American GDP.

US Exports have doubled as a percent of GDP since 1975.

Closed vs. Open EconomiesA closed economy focuses only on the domestic price and the open economy

trades for the lower world price.

25

Page 26: Why do people trade?

Balance of Trade vs. Balance of Payments

Page 27: Why do people trade?

Balance of TradeNet Exports (XN) = Exports – ImportsTrade Surplus = Exporting more than is importedTrade Deficit (aka. trade gap) = Exporting less than is imported

Page 28: Why do people trade?

Balance of Trade

Page 29: Why do people trade?

Balance of Payments (BOP)Balance of trade includes only goods and service but balance of payments considers ALL international transactions.

• The balance of payments is a broader measure of international trade.

Details: The BOP summary is within a given yearPrepared in the domestic country’s currency

Ex. If accounting the BOP of the U.S. it would be in the Dollar. The balance of payments is made up of two accounts. The current account and the capital account.

Page 30: Why do people trade?

Which countries have the highest account surpluses and account deficits?

Page 31: Why do people trade?

Current AccountThe Current Account is made up of three parts:1. Trades in Goods and Services (Net Exports)-

Difference between a nation’s exports of goods and services and its imports of goods and services

Ex: Toys imported from China, US cars exported to Mexico

2. Investment Income- income from the factors of productions including payments made to foreign investors.

Ex: Money earned by Japanese car producers in the US3. Net Transfers- Money flows from the private or

public sectorsEx: donations, aids and grants, official assistance

Page 32: Why do people trade?

Capital (Financial) AccountThe Capital Account measures the purchase and

sale of financial assets abroad.Purchases of things that stay in the foreign country.Examples:

– US company buys a hotel in Russia– A Korean company sells a factory in Ohio– Dividends earned by Chinese citizens in the New

York Stock Exchange (NYSE)– Australian company owns local Mall

Page 33: Why do people trade?

Current or Capital Account?Identify if the examples are counted in the current or

capital account and determine if it is a credit or debit for the US.

1. Bill, an American, invests $20 million in a ski resort in Canada

2. A Korean company sells vests to the US Military3. A US company, Boeing, sells twenty 747s to France4. A Chinese company buys a shopping mall in San Diego5. An illegal immigrant sends a portion of his earning to

his family6. An German investor buys $50,000 US Treasury Bonds7. Italian tourists spend 5 million in the US while

American tourists spend 8 million in Italy.

Page 34: Why do people trade?

Current or Capital Account?Identify if the examples are counted in the current or

capital account and determine if it is a credit or debit for the US.

Practice1. U.S. income increase relative to other countries. Does

the balance of trade move toward a deficit or a surplus?- U.S. citizens have more disposable income - Americans import more- Net exports (Xn) decrease- The current account balance decreases and moves

toward a deficit.2. If the U.S. dollar depreciates relative to other

countries does the balance of trade move toward a deficit or a surplus?- US exports are desirable- America exports more- Net exports (Xn) increase- The current account balance decreases and moves

toward a surplus.

Foreign Exchange(aka. FOREX)

Exchange Rate = Relative Price of Currencies

Page 38: Why do people trade?

Video: Down and Out Dollar

Page 39: Why do people trade?

Exports and Imports1. US sells cars to Mexico2. Mexico buys tractors from Canada3. Canada sells syrup t the U.S.4. Japan buys Fireworks from Mexico For all these transactions, there are

different national currencies.Each country must be paid in their own

currencyThe buyer (importer) must exchange their

currency for that of the sellers (exporter).

Page 40: Why do people trade?

The turnover in FOREX markets is almost $4 trillion (USD) a day

Currency CodesUSD = US Dollar EUR = Euro JPY = Japanese Yen GBP = British Pound CHF = Swiss Franc CAD = Canadian DollarAUD = Australian Dollar NZD = New Zealand Dollar

Page 41: Why do people trade?
Page 42: Why do people trade?

Exchange RatesIn the FOREX market we only look at two

countries/currencies at a time Ex: US Dollars and British Pounds

We examine the price of one currency in terms of the other currency. Ex:$2 = £1The Exchange Rate depends on which currency you are converting.The price of one US Dollar in terms of Pounds is

1 Dollar = £1/$2 = £.5The price of one Pound in terms of Dollars is

1 Pound = $2/£1 = $2

Page 43: Why do people trade?

What happens if you need more dollar to buy one pound (the price for a pound

increases)? Ex: From $2=£1 to $5=£1

•The U.S. Dollar DEPRECIATES relative to the Pound.

Depreciation•The loss of value of a country's currency with respect to a foreign currency

•More units of dollars are needed to buy a single unit of the other currency.

•The dollar is said to be “Weaker”

Page 44: Why do people trade?

What happens if you need less dollar to buy one pound (the price for a pound

decreases)? Ex: From $2=£1 to $1=£4

•The U.S. Dollar APPRECIATES relative to the Pound.

Appreciation•The increase of value of a country's currency with respect to a foreign currency

•Less units of dollars are needed to buy a single unit of the other currency.

•The dollar is said to be “Stronger”

FOREX Supply and Demand Simplified

Imagine a huge table with all the different currencies from every country

This is the Foreign Exchange Market!Just like at a product market, you can’t take

things without paying.If you demand one currency, you must supply

your currency.Ex: If Canadians what Russian Rubles. The demand for Rubles in the FOREX market will increase and the supply of Canadian Dollars will increase.

Page 47: Why do people trade?

FOREX ShiftersLet’s use the example of the US Dollar and the British Pound

Page 48: Why do people trade?

1. Changes in Tastes-Ex: British tourists flock to the U.S…

Demand for U.S. dollars increases (shifts right)Supply of British pounds increases (shifts right)

Pound-depreciates Dollar-appreciates

2. Changes in Relative Incomes (Resulting in more imports)-

Ex: US growth increase US incomes….U.S. buys more imports…U.S. Demand for pounds increasesSupply of U.S. dollars increases

Pound- appreciatesDollar- depreciates

Page 49: Why do people trade?

3. Changes in Relative Price Level (Resulting in more imports)-

Ex: US prices increase relative to Britain….U.S. demand for cheaper imports increases… U.S. demand for pounds increasesSupply of U.S. dollars increases

Pound- appreciatesDollar- depreciates

4. Changes in relative Interest Rates-Ex: US has a higher interest rate than Britain.

British people want to invest in USCapital Flow increase towards the USBritish demand for U.S. dollars increases… British supply more pounds

Pound-depreciatesDollar- appreciates

Page 50: Why do people trade?

PracticeFor each of the following examples, identify what will

happen to the value of US Dollars and Japanese Yen. 1. American tourists increase visits to Japan. 2. The US government significantly decreases

personal income tax.3. Inflation in the Japan rises significantly faster

than in the US.4. Japan has a large budget deficit that

increases Japanese interest rates. 5. Japan places high tariffs on all US imports.6. The US suffers a larger recession.7. The US Federal Reserve sells bonds at high

interest rates. How do these scenarios affect exports and imports?

Page 51: Why do people trade?

PracticeFor each of the following examples, identify what will

happen to the value of US Dollars and Japanese Yen. 1. USD depreciates and Yen appreciates 2. USD depreciates and Yen appreciates 3. USD appreciates and Yen depreciates4. USD depreciates and Yen appreciates5. USD depreciates (Demand Falls) and Yen

appreciates (Supply Falls)6. USD appreciates (Supply Falls) and Yen

depreciates (Demand Falls)7. USD appreciates and Yen depreciatesScenarios 1, 2, and 4 will increase US exports because

US products are now relatively “cheaper”
